How to make progress bar in swing and making it disable for closing, minimizing and maximizing. It will automatically dispose off after complete application execution?

package net.codejava.swing.download;

import java.awt.FlowLayout;

import javax.swing.JFrame;

import javax.swing.JProgressBar;

public class ProgressBarDemo extends JFrame{

              /**

        *

        */

       private static final long serialVersionUID = 1L;

              JProgressBar jb;

              int i = 0, num = 0;

              ProgressBarDemo() {

                     setTitle("Launching ");

                     jb = new JProgressBar(0, 1000);

                     jb.setBounds(30, 30, 150, 40);

                     jb.setValue(0);

                     jb.setStringPainted(true);

                     add(jb);

                     setSize(250, 150);

                     setLayout(new FlowLayout());

//user can not close the progress bar and stop application processing

                     setEnabled(false);

              }

              public void iterate() {

                     while (i <= 1000) {

                           if(jb.isEnabled()){

                           jb.setValue(i);

                           i = i + 20;

                           System.out.println(i);

                           }

                           else{         }

              public void progress () {

                     while (i <= 1000) {

                         

                           jb.setValue(i);

                           i = i + 30;

                        

                           try {

                                  Thread.sleep(100);

                           } catch (Exception e) {

                           }

                     }

              }

              public static void main(String[] args) {

                     ProgressBarDemo m = new ProgressBarDemo();

                     m.setVisible(true);

                     m.progress();

//                  closing the frame after 100%

                     m.dispose();

                    

              }

}
